Field studies were carried out in all sampling areas, with groups of 2-4 people, usually with tent camps. In addition, in 3 sampling areas, 5 census studies were carried out with groups of 10-30 persons. Direct and indirect census methods were used in all census in sampling units. Besides point and line transect observations, camera traps and thermal camera records were used in direct observations.
